West Midlands Police said that the caller contacted them as he "wished to report her for breaching the Sale of Goods Act", reports The Mirror.

A spokesperson for the police said: "A 999 call was received by police at around 7.30pm on Tuesday evening from a man wishing to complain about a sex worker he had met on a hotel car park.

"The caller claimed that the woman had made out she was better looking than she actually was... When he raised this issue with the woman concerned, she allegedly took his car keys, ran away from the car and threw them back at him, prompting him to call police."

The man didn't give the police any of his details, but they tracked him down and sent him a letter of warning for wasting police time.

In the call to 999, the complainant can be heard saying that the woman had "mis-described" and "misrepresented herself".

He said to the call-handler: "I arranged to meet with her, but beforehand I asked for a description of her - 'Give me an honest description otherwise when I get there I'm not going to use your services'.
